Verification done for focal-proposed (partman-crypto) --- 1) Booted the Ubuntu 20.04.1 Desktop ISO. 2) Launched a terminal, extracted the .udeb and copied over the crypto-base.sh file. 3) Performed installation to encrypted disk without the preseed option (default). 4) Performed installation to encrypted disk with the preseed option (testing).
On both cases, the installation finishes successfully, and the system can boot. The LUKS header version is used as expected (LUKS2 by default, LUKS1 w/ option) Details: --- Launch terminal: $ wget https://launchpad.net/ubuntu/+archive/primary/+files/partman-crypto_101ubuntu4.1_amd64.udeb $ dpkg-deb -x partman-crypto_101ubuntu4.1_amd64.udeb udeb $ sudo cp udeb/lib/partman/lib/crypto-base.sh /lib/partman/lib/crypto-base.sh $ grep luksopts /lib/partman/lib/crypto-base.sh local mapping device cipher iv size pass luksopts luksopts="$RET" log "Additional options for luksFormat: '$luksopts'" log-output -t partman-crypto /sbin/cryptsetup -c $cipher-$iv -h $hash -s $size $luksopts luksFormat $device $pass Launch ubiquity / Install Ubuntu 20.04.1 Desktop to Encrypted LVM device.
